Hi everyone. This is just a short post to help you remember the functions of the Vestibular System. Memorising this always gives me a vertigo. ;)
The Vestibular System has 2 components :
1. Semicircular canals
2. Utricle and Saccule.
So the Vestibular System detects the following :
Angular Acceleration/Rotational movements.
Position of Head in space.
So the Semi circular canals are concerned with Angular Acceleration. You can remember that as :
Circle = Rotates ; So SCC detect Rotational movements or Angular Acceleration
The rest are functions of Utricle and Saccule.
Remember : GPL - Girls Premiere League.
For : Gravity, Position of Head and Linear acceleration.
Now remember :
Saccule - NOT Sleeping line. So Vertical movements.
Utricle - Horizontal (since sleeping line was not Saccule it will be Utricle)
Another way would be "UHH' Utricle for Horizontal.
Hope this helped you.
Happy studying ! :)
